Ubuntu update problem

I have noticed again 2 problems with Ubuntu 18.10 updates.

1. I had Ubuntu on a US update location using "software & update" application and did not receive any updates for several days. I changed to another update location and a "ubase" update was then made available.

2. I have selected "when there are security updates" "download and install automatically" but security updates are not install automatically. I see on occasional updates security updates pending.

The first issue has occurred twice. Is their a known problem with updates?

If you notice different mirrors have different update schedules.https://launchpad.net/ubuntu/+archivemirrors
So when switching mirrors you may have different updates.
Best not to switch often as then you can get into out of sync issues.

Is there a way to search for the mirror "mirror.us.leaseweb.net" as the names listed in the United states such as "xTom" and "layeronline" don't identify who they are. I suspect this mirror may not be providing correct updates
